The answers are blurry and hard to read. If you repost this question with a clearer picture, I would be happy to try and answer as best I can! :)
Answer:

Step-by-step explanation:
Given:
The table is given as:
x 0 4 7 8
y 0 24 42 48
The relationship between 'x' and 'y' is a proportional relationship.
A proportional relationship is one in which one variable varies directly with the other by a factor of 'k' also known as constant of proportionality and 
A proportional relationship is given as:

Now, we plug in 'x' and 'y' values and find the value of 'k'.
Let 

Therefore, the constant of proportionality is 6. Hence the complete equation is given as:

Answer:
343
Step-by-step explanation:
There are quarters(25¢), loonies ($1), and toonies ($2)
And total number of coins is 9
If loonies ($1), and toonies ($2) are one, then quarters(25¢) is 7
If quarters(25¢), and toonies ($2) are one, then loonies ($1)is 7
If loonies ($1), and quarters(25¢) are one, then toonies ($2) is 7
So possible number number of combination for an item that cost between $10 and $12 is
= 1^3 * 1^3 * 7^3
= 343
hope this helps, stay safe :)

Answer: (C) 8/30</h3>
===================================================
Explanation:
There are 5+3 = 8 people in choir and running club. I added the values in the overlapped region of the circles "choir" and "running club".
This is out of 2+5+6+7+3+4+3 = 30 people total.
Divide the two results to form the fraction 8/30
Ideally we should reduce to get 4/15, but your teacher has chosen not to reduce.
